Review on NutraBio PRE Workout Powder - Energize Your workout with Long-lasting Stamina, Enhanced Concentration, and Enhanced Endurance - Expertly Formulated with Beta Alanine, Creatine, Caffeine, Electrolytes - 20 Servings - Grape Berry Crush by Stephanie Young

I've been using this pre-workout for about a year. If you're familiar with pre-workouts, then you should know that the line itself plays an important part - I haven't developed a tolerance for the ingredients. It still gives me great workouts (especially when combined with a good night's sleep). If you take the time to research the ingredients and dosages, you will find that everything is clinically dosed, meaning that enough of each ingredient is added to produce the effects shown in the clinical studies of that ingredient. The taste is one of the best in the Prrworkout. I usually mix mine with more water than recommended because I generally like the lighter flavor. Two tips: First, shake occasionally while drinking. Obviously one of the ingredients is insoluble and you will see it sink to the bottom. Second, ALWAYS ORDER FROM NUTRABIO LABS. Other vendors on Revain ship junk items that are lumpy, smelly, and taste bad. The product has always been good when ordered from Nutrabio through Revain.
